The 0560 is a great knife, but it's very big and chunky, feels good in the hand and is an excellent user that can take anything. However, the size is an issue and I didn't really like the texturing on the titanium. Smooth, and excellent knife. But, I wouldn't get it, I just didn't like the way it handled all that well, big, rough.
I do want the ZT 0560CBCF though, The steel, smoothness, materials, and how it feels over the standard 0560 made me fall in love with it.
The Strider SnG is likely the best Strider out there. It's not too big and not too small. Awesome ergos, great looks, tough as nails, and a great warranty. I personally prefer the CC over the Lego or GG. While all of them are great, the Lego and GG are a little rough. Not to mention they're flat compared to the CC. My only issue with my SnG was that the big lock bar cutout was in a place that always got stuck on my pocket and made it difficult to put in the pocket and to pull out of the pocket. That's the whole reason I got rid of it. The CC is a bit more rounded for better grip in my opinion, smoother feel, and the lock bar cutout doesn't seem to get in the way as much. You really can't go wrong with the Strider, it's a tank, however, it could be a bit thick for every EDC task you may need it for.
The Sebenza, is a classic for a reason. It is literally the perfect pocket knife. It's classy looking and holds a lot of cutting power behind it. It's relatively thin and light for easy carry, great ergos, the insingo blade is perfect for EDC, the fit and finish and tolerances on this knife are perfect. While the Sebenza looks classy and really is, it was made to work. You can use it for just plain EDC tasks and for harder use. It makes the perfect all around EDC, handling anything and everything you need. Thin enough for slicing and delicate work, thick and tough enough for the harder tasks.
For me, the Sebenza wins. It's perfect and beats the Strider in fit and finish and tolerances. It also wins for being the most versatile of the 3 you mentioned.
If you really want a big beefy blade, go for the ZT 0560cbcf, you can't beat the steel, materials, and feel of this over the standard 0560 and the Strider. It's smooth, buttery, beautiful, made with top notch materials, and still a hell of a work horse.
So really I would narrow it down to the Sebenza and 0560cbcf. Both are beautiful knives made to handle all of your EDC needs, made perfectly, smooth, and wonderful. All around EDC - Seb for me. Big Beefy Beautiful and still a good EDC - 0560cbcf.
